Given numbers are 449,446,137,642,164

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 449,446,137,642,164 is 722138752956.

Find LCM of 449,446,137,642,164 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 449 x 223 x 137 x 321 x 82 = 722138752956

Therefore, the lowest common multiple of 449,446,137,642,164 is 722138752956.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

449 x 446 x 137 x 642 x 164 = 2888555011824

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

449 : 1, 449

446 : 1, 2, 223, 446

137 : 1, 137

642 : 1, 2, 3, 6, 107, 214, 321, 642

164 : 1, 2, 4, 41, 82, 164

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 449,446,137,642,164, is 1.

Now, the common factors can be found like this.

449:449

446:2x 223

137:137

642:2x 3x 107

164:2x 2x 41

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 2888555011824/(1x4)

LCM = 2888555011824/4

LCM = 722138752956

Thus, we can understand that the LCM of 449,446,137,642,164 is 722138752956.
